For this purpose, dry blends of glass beads with and without organosilane coupling agents and polyamide powder were prepared and processed into tensile specimens on an EOS P396. The samples were tested both in the dry state and after an accelerated conditioning in a climate chamber. Furthermore, FEM simulations were performed to model the limiting cases of optimum adhesion and no adhesion. By correlating the tensile tests with the simulation results and by analyzing the fracture surfaces, it was shown that the filler matrix adhesion is sufficient in the dry state but is strongly degraded by conditioning. Even the presence of various organosilane thin films could not prevent a strong deterioration of the filler-matrix adhesion and the associated deterioration of the mechanical properties. Since a comparison with an injection molded sample of the same polymer filler combination shows identical behavior after conditioning, it is assumed that this problem is not limited to additively manufactured parts." author: - first_name: Ivo full_name: Kletetzka, Ivo last_name: Kletetzka - first_name: Maren full_name: Kosanke, Maren last_name: Kosanke - first_name: Dennis full_name: Meinderink, Dennis last_name: Meinderink - first_name: Vanessa full_name: Neßlinger, Vanessa last_name: Neßlinger - first_name: Guido full_name: Grundmeier, Guido last_name: Grundmeier - first_name: Hans-Joachim full_name: Schmid, Hans-Joachim last_name: Schmid citation: ama: Kletetzka I, Kosanke M, Meinderink D, Neßlinger V, Grundmeier G, Schmid H-J.

This has already been investigated intensively by various authors. However, the ageing of the material at ambient temperatures during shelf life has not been the focus so far. The need to analyse the shelf life can be derived from an ecological and economic point of view. This work is focusing on the shelf life of PA2200 (PA12). To reduce the potential influences of powder production fluctuations, two different powder batches stored for 5.5 years and 6.5 years are investigated and compared to a reference powder produced 0.5 years before these investigations. Multiple powder analyses and part characterisations have been performed. A significant yellowing and molecular chain length reduction can be derived from the measurement results. Whereas the influence on mechanical part performance was minor, the parts built with the stored powders are more yellowish. As it is most likely that this is due to the consumption of polyamide stabilisers, it can be assumed that these parts will be subject to significantly faster ageing. Therefore, it is still not recommended to use the stored powders for critical parts or light intense and humid environments. author: - first_name: Sven Helge full_name: Klippstein, Sven Helge id: '71545' last_name: Klippstein - first_name: Ivo full_name: Kletetzka, Ivo id: '50769' last_name: Kletetzka - first_name: Ilknur full_name: Sural, Ilknur last_name: Sural - first_name: Hans-Joachim full_name: Schmid, Hans-Joachim id: '464' last_name: Schmid orcid: 000-0001-8590-1921 citation: ama: Klippstein SH, Kletetzka I, Sural I, Schmid H-J.

Für kleine Losgrößen bietet sich hier insbesondere das Fertigungsverfahren des Drückwalzens an. Der konventionelle, industriell genutzte Drückwalzprozess stößt allerdings aufgrund der Prozesskomplexität hinsichtlich der Reproduzierbarkeit an seine Grenzen. Dies wird in der Praxis teilweise durch personengebundenes Erfahrungswissen kompensiert. Auch ist es nicht möglich, Bauteileigenschaften definiert einzustellen. Aus diesem Grund bietet der Einsatz einer neuartigen Eigenschaftsregelung Chancen zur Weiterentwicklung des Fertigungsprozesses und die Möglichkeit zur Prozessautomatisierung. Hier werden die Werkzeugbahnen abhängig einer Online-Eigenschaftsmessung über eine zusätzliche Reglerkaskade manipuliert. Die Entwicklung einer solchen Eigenschaftsregelung erfordert den Einsatz geeigneter, modellbasierter Entwurfsmethoden. In diesem Beitrag wird daher ein regelungstechnisches Systemmodell für das Drückwalzen metastabiler austenitischer Edelstähle vorgestellt. Das Simulationsmodell weist aufgrund seiner Echtzeitfähigkeit neben dem Einsatz als reines Entwurfsmodell weitere Nutzungsmöglichkeiten z.B. in Beobachtern auf und grenzt sich somit von domänenspezifischen Simulationstools wie der FEM ab." author: - first_name: Lukas full_name: Kersting, Lukas last_name: Kersting - first_name: Bahman full_name: Arian, Bahman id: '36287' last_name: Arian - first_name: Julian full_name: Rozo Vasquez, Julian last_name: Rozo Vasquez - first_name: Ansgar full_name: Trächtler, Ansgar id: '552' last_name: Trächtler - first_name: Werner full_name: Homberg, Werner id: '233' last_name: Homberg - first_name: Frank full_name: Walther, Frank last_name: Walther citation: ama: Kersting L, Arian B, Rozo Vasquez J, Trächtler A, Homberg W, Walther F.

Climate change, rare resources and industrial transformation processes lead to a rising demand of multi-complex lightweight forming parts, especially in aerospace and automotive sectors. In these industries, flow forming is often used to produce cylindrical forming parts by reducing the wall thickness of tubular semifinished parts, e.g. for the production of hydraulic cylinders or gear shafts. The complexity and functionality of flow forming workpieces could be significantly increased by locally graded microstructure and geometry structures. This enables customized complex hardness distributions at wear surfaces or magnetic QR codes for a unique, tamper-proof product identification. The production of those complex, 2D (axial and angular) graded forming parts currently depicts a great challenge for the process and requires new solutions and strategies. Hence, this paper proposes a novel control strategy that includes online measurements from an absolute encoder to determine the angular workpiece position. Workpieces of AISI 304L stainless steel with 2D-graded structures are successfully manufactured using this new strategy and analyzed regarding the possible accuracy and resolution of the gradation. At this point, a dependency of the gradations on the sensor and actuator dynamics, accuracy and geometry could be noted. It is further evaluated how the control strategy could be extended by an observer-based closed-loop property control approach to enhance the accuracy of the suggested strategy. author: - first_name: Lukas full_name: Kersting, Lukas last_name: Kersting - first_name: Bahman full_name: Arian, Bahman id: '36287' last_name: Arian - first_name: Julian full_name: Rozo Vasquez, Julian last_name: Rozo Vasquez - first_name: Ansgar full_name: Trächtler, Ansgar id: '552' last_name: Trächtler - first_name: Werner full_name: Homberg, Werner id: '233' last_name: Homberg - first_name: Frank full_name: Walther, Frank last_name: Walther citation: ama: 'Kersting L, Arian B, Rozo Vasquez J, Trächtler A, Homberg W, Walther F.

The study investigates two different ways of guiding the addressee of an explanation - an explainee, through action demonstration: contrastive and non-contrastive. Their effect was tested on attention to specific action elements (goal) as well as on event memory. In an eye-tracking experiment, participants were shown different motion videos that were either contrastive or non-contrastive with respect to the segments of movement presentation. Given that everyday action demonstration is often multimodal, the stimuli were created with re- spect to their visual and verbal presentation. For visual presentation, a video combined two movements in a contrastive (e.g., Up-motion following a Down-motion) or non-contrastive way (e.g., two Up-motions following each other). For verbal presentation, each video was combined with a sequence of instruction descriptions in the form of negative (i.e., contrastive) or assertive (i.e., non-contrastive) guidance. It was found that a) attention to the event goal increased for this condition in the later time window, and b) participants’ recall of the event was facilitated when a visually contrastive motion was combined with a verbal contrast.

Effizienz bedeutet in diesem Fall, dass die Produkte kostengünstig und bedarfsgerecht hergestellt werden. Der Trend geht hierbei auch in der Massenproduktion zu einer flexiblen Produktion, um das gebundene Kapital zu reduzieren und zeitnah auf Kundenwünsche reagieren zu können. Dies führt zu einem häufigeren Umrüsten der Werkzeuge in den Maschinen und somit zu einem immer häufigeren Einrichten der Prozesse.In dieser Arbeit wird eine Systematik für ein adaptives Einrichtassistenzsystem entwickelt, welches den Maschinenbediener beim Einrichten mithilfe eines definierten Vorgehens durch den Prozess leitet. Der Bediener wird dabei unterstützt die momentane Produktqualität zu bewerten und bekommt einen quantitativen Vorschlag zur Variation der Justagemöglichkeiten. So kann der Einrichtprozess zielgerichteter und fehlerfreier durchgeführt werden. Ermöglicht wird dies durch die Abbildung des notwendigen Expertenwissens in datengetriebenen Modellen. Mithilfe des so abgebildeten Expertenwissens werden optimierte Einstellungen berechnet und am Werkzeug eingestellt. Es ist nicht davon auszugehen, dass das virtualisierte Expertenwissen die Realität allumfassend abbilden und alle akuten Umwelteinflüsse messtechnisch ermittelt werden können. Etwaige Abweichungen der Produktqualität werden direkt in der entwickelten Optimierung und bei Bedarf mithilfe der vorgeschlagenen Kompensationsstrategie eliminiert.Die Systematik wird anhand eines Folgeverbundprozesses validiert. Nach der Analyse des Prozesses werden die wesentlichen Komponenten für das System entwickelt und mithilfe von Versuchen und Simulationen die Funktionsfähigkeit erfolgreich nachgewiesen. - lang: eng text: A trend in production are individualized products and thus a higher number of variants, which are ideally produced by efficient production processes. In this case, efficiency means that the products are manufactured at low cost and in line with demand. This trend, flexible manufacturing, is also valid for mass production, in order to reduce tied up capital and still be able to react promptly to customer demands. This leads to more frequent retooling in the machines and thus also to an increasingly frequent setting up of the processes.In this thesis, a systematic for an adaptive set-up assistant is developed, which guides the machine operator through the process during setup. The machine operator is supported in evaluating the current product quality and receives a quantitative proposal for the variation of the adjustment possibilities. Thus, the set-up process can be carried out in a more targeted and error-free manner. This is made possible by mapping the necessary expert knowledge in data-driven models. The expert knowledge is used to calculate optimized settings and adjust them on the tool. It cannot be assumed that virtualized expert knowledge will comprehensively map reality and that all acute environmental influences can be measured. Any deviations in product quality are directly eliminated in the developed optimization and, if necessary, with a proposed compensation strategy.The system is validated with a progressive tool. After analyzing the process, the essential components for the system are developed and their functionality is successfully demonstrated by means of tests and simulations. author: - first_name: Manuel full_name: Gräler, Manuel last_name: Gräler citation: ama: Gräler M.

We are interested in dynamic scenarios where data is sampled progressively, and learning is done in an incremental rather than a batch mode. We seek efficient incremental algorithms for computing feature importance (FI). Permutation feature importance (PFI) is a well-established model-agnostic measure to obtain global FI based on feature marginalization of absent features. We propose an efficient, model-agnostic algorithm called iPFI to estimate this measure incrementally and under dynamic modeling conditions including concept drift. We prove theoretical guarantees on the approximation quality in terms of expectation and variance. To validate our theoretical findings and the efficacy of our approaches in incremental scenarios dealing with streaming data rather than traditional batch settings, we conduct multiple experimental studies on benchmark data with and without concept drift. author: - first_name: Fabian full_name: Fumagalli, Fabian last_name: Fumagalli - first_name: Maximilian full_name: Muschalik, Maximilian last_name: Muschalik - first_name: Eyke full_name: Hüllermeier, Eyke last_name: Hüllermeier - first_name: Barbara full_name: Hammer, Barbara last_name: Hammer citation: ama: 'Fumagalli F, Muschalik M, Hüllermeier E, Hammer B.
